1. irrational

   That is absurd which is contrary to the first principles of reasoning; as, that a part should be greater than the whole is absurd. A paradoxical statement appears at first thought contradictory or absurd, while it may be really true. Anything is irrational when clearly contrary to sound reason, foolish when contrary to practical good sense, silly when petty and contemptible in its folly, erroneous when containing error that vitiates the result, unreasonable when there seems a perverse bias or an intent to go wrong. Monstrous and preposterous refer to what is overwhelmingly absurd; as, "O monstrous! eleven buckram men grown out of two," Shakespeare 1 King Henry IV, act ii, sc. 4. The ridiculous or the nonsensical is worthy only to be laughed at. The lunatic's claim to be a king is ridiculous; the Mother Goose rimes are nonsensical. Compare INCONGRUOUS.

2. Yaakov Menken:

   Repeatedly accusing the Jewish state of Israel of ‘genocide,' ‘apartheid,' and other fictitious crimes while praising China, a country that is putting Muslims in internment camps, indicates an irrational hatred of Jews and not a concern for human rights, with regards to Jews, diversity heads seem to share much in common with grand wizards of the Ku Klux Klan, and it is clear that the entire field needs to be reevaluated before more Jewish students are placed at unnecessary risk.

3. Andrew Bernstein:

   For the first time in history, the rational and the good are fully armed in the battle against evil. Here we finally find the answer to our paradox; now we can understand the nature of the social power held by evil. Ultimately, the evil, the irrational, truly has no power. The evil men’s control of morality is transient; it lives on borrowed time made possible only by the errors of the good. In time, as more honest men grasp the truth, evil’s stranglehold will be easily broken.

5. Rick DePiro:

   It's better to be a janitor in heaven Than to sit on a throne in hell It's better to sweep the streets of gold Than to have illegitimate unearned wealth. We live today in a world of much irrational entitlement and participation trophies. Earn your place, fight for your rights, stand with honor and for God's sake, keep quiet unless you actually know what you're talking about!
